Which architecture design pattern should I use for an Arduino project?

I want to determine what architecture design pattern I should use for the following example. I have an Arduino reading temperature signals. This data is read in every second and the data is being preocessed by a python script and stored in a database. The data is also displayed on a web server.

I am not too familiar with architecture design patterns so not sure what to pick, but personally I was thinking Layered architecture?

Any help is appreciated.
